2 Definitions

Natural Language Processing (NLP) is a field of artificial intelligence that focuses on the interaction between computers and human language. It involves the development of algorithms and systems that can understand, interpret, and generate human language in a valuable way. NLP encompasses a range of techniques and tools that allow computers to process, analyze, and sometimes mimic human speech and text, enabling applications such as translation services, sentiment analysis, and conversational agents. The goal of NLP is to bridge the gap between human communication and computer understanding to enhance the usability and accessibility of technology.

Large Language Models (LLMs) are advanced artificial intelligence systems designed to understand, generate, and translate human language at a vast scale. They are built using deep learning techniques, particularly neural networks, trained on extensive collections of text data. This training enables LLMs to predict and generate language sequences with remarkable fluency, which facilitates a wide array of NLP tasks such as conversational AI, text completion, translation, and content creation. LLMs, such as OpenAI's GPT series, stand out for their ability to handle complex language tasks that often require a nuanced understanding of context and semantics.

Large Multimodal Models (LMMs) are sophisticated AI systems capable of processing and generating information across different types of data, such as text, images, and audio. These models integrate multiple modes of input to understand and perform tasks that reflect human-like cognitive abilities. By learning patterns and features from diverse datasets, LMMs can perform complex functions, like recognizing objects in images and associating them with natural language descriptions, enabling more comprehensive AI applications that go beyond single-modality tasks.

3 Current Use Cases
